selftests: netconsole: Increase port listening timeout

2026-02-13T20:22:36+00:00

wait_for_port() can wait up to 2 seconds with the sleep and the polling
in wait_local_port_listen() combined. So, in netcons_basic.sh, the socat
process could die before the test writes to the netconsole.

Increase the timeout to 3 seconds to make netcons_basic.sh pass
consistently.

selftests: netconsole: validate target resume

2026-01-22T03:09:12+00:00

Introduce a new netconsole selftest to validate that netconsole is able
to resume a deactivated target when the low level interface comes back.

The test setups the network using netdevsim, creates a netconsole target
and then remove/add netdevsim in order to bring the same interfaces
back. Afterwards, the test validates that the target works as expected.

Targets are created via cmdline parameters to the module to ensure that
we are able to resume targets that were bound by mac and interface name.

selftests/net: Make NetDrvContEnv support queue leasing

2026-01-20T10:58:50+00:00

Add a new parameter `lease` to NetDrvContEnv that sets up queue leasing
in the env.

The NETIF also has some ethtool parameters changed to support memory
provider tests. This is needed in NetDrvContEnv rather than individual
test cases since the cleanup to restore NETIF can't be done, until the
netns in the env is gone.

selftests/net: Add env for container based tests

2026-01-20T10:58:50+00:00

Add an env NetDrvContEnv for container based selftests. This automates
the setup of a netns, netkit pair with one inside the netns, and a BPF
program that forwards skbs from the NETIF host inside the container.

Currently only netkit is used, but other virtual netdevs e.g. veth can
be used too.

Expect netkit container datapath selftests to have a publicly routable
IP prefix to assign to netkit in a container, such that packets will
land on eth0. The BPF skb forward program will then forward such packets
from the host netns to the container netns.

Run the test against HW GRO and LRO. NICs I have pass the base cases.
Interestingly all are happy to build GROs larger than 64k.

selftests: drv-net: psp: Better control the used PSP dev

2026-01-10T22:44:05+00:00

The PSP responder fails when zero or multiple PSP devices are detected.
There's an option to select the device id to use (-d) but it's
currently not used from the PSP self test. It's also hard to use because
the PSP test doesn't dump the PSP devices so can't choose one.
When zero devices are detected, psp_responder fails which will cause the
parent test to fail as well instead of skipping PSP tests.

Fix both of these problems. Change psp_responder to:
- not fail when no PSP devs are detected.
- get an optional -i ifindex argument instead of -d.
- select the correct PSP dev from the dump corresponding to ifindex or
- select the first PSP dev when -i is not given.
- fail when multiple devs are found and -i is not given.
- warn and continue when the requested ifindex is not found.

Also plumb the ifindex from the Python test.

With these, when there are no PSP devs found or the wrong one is chosen,
psp_responder opens the server socket, listens for control connections
normally, and leaves the skipping of the various test cases which
require a PSP device (~most, but not all of them) to the parent test.
This results in output like:

ok 1 psp.test_case # SKIP No PSP devices found
[...]
ok 12 psp.dev_get_device # SKIP No PSP devices found
ok 13 psp.dev_get_device_bad
ok 14 psp.dev_rotate # SKIP No PSP devices found
[...]

selftests: drv-net: introduce Iperf3Runner for measurement use cases

2025-12-02T01:18:41+00:00

GenerateTraffic was added to spin up long-running iperf3 load, mainly
to drive high PPS background traffic. It was never meant to provide
stable throughput numbers, and trying to repurpose it for measurement
does not make sense.

Introduce Iperf3Runner to allow tests to split out server/client
configuration, control start/stop, and collect JSON output for
analysis. This makes it possible to measure bandwidth directly when
validating egress shaping.

GenerateTraffic stays as the background load generator, reusing the
common iperf3 helpers under the hood.

selftests: netconsole: remove log noise due to socat exit

2025-12-01T20:06:55+00:00

This removes some noise that can be distracting while looking at
selftests by redirecting socat stderr to /dev/null.

Before this commit, netcons_basic would output:

Running with target mode: basic (ipv6)
2025/11/29 12:08:03 socat[259] W exiting on signal 15
2025/11/29 12:08:03 socat[271] W exiting on signal 15

2025/11/29 12:08:10 socat[435] W exiting on signal 15
extended : ipv4 : Test passed

After these changes, output looks like:

Running with target mode: basic (ipv4)
basic : ipv4 : Test passed
Running with target mode: extended (ipv6)

selftests: net: py: read ip link info about remote dev

2025-11-21T02:19:29+00:00

We're already saving the info about the local dev in env.dev
for the tests, save remote dev as well. This is more symmetric,
env generally provides the same info for local and remote end.

While at it make sure that we reliably get the detailed info
about the local dev. nsim used to read the dev info without -d.
